CPP and EI Overpayment With More Than One Employer in 2026
Someone who earned $60,000 at one employer in the first half of 2026 and $60,000 at another in the second half has had $6,931.76 of CPP and $1,956.00 of EI taken off their pay across the year. The most one worker can owe through employment for 2026 is $4,646.45 of CPP and $1,123.07 of EI. The return gives back $3,118.24 of the difference, $2,285.31 of CPP on line 44800 and $832.93 of EI on line 45000, and nobody did anything wrong to produce it. Each employer deducted exactly what CRA instructs it to deduct.
A CPP and EI overpayment is the ordinary consequence of holding more than one job in a year, and at the top end it is larger than that. Two employers who each pay above $85,000 produce a refund of $5,769.52, a full year of both contributions handed back. The money is not lost at any point. It is out of the worker’s hands from the pay period it came off until the 2026 return is assessed, and that use of it is the whole cost.
Every figure below is CRA’s published 2026 amount, data as of November 13, 2026, for a resident of a province or territory other than Quebec. Quebec makes the same correction through QPP rather than CPP, with Form RC381 where the year mixed the two, and claims the excess on line 452 of the Revenu Quebec return.
Each employer starts the ceilings over
CPP and EI are capped by the year, but payroll runs by the job, and CRA’s instruction to every employer is to ignore what happened at any other one. Chapter 6 of CRA’s T4127 payroll deductions formulas, 122nd Edition, effective January 1, 2026, puts it without hedging:
“Each employer needs to deduct CPP contributions based on the employee’s pensionable income, without regard to any other earnings the employee may have had with another employer in the same year. Accordingly, you must use the maximum above even if the employee works for you less than 12 months.”
CRA’s T4001, the employers’ guide to payroll deductions and remittances, says it twice more, once for each program, and takes on the job-change case by name. The CPP paragraph, which still quotes the 2025 ceiling:
“The annual maximum pensionable earning ($71,300 for 2025) applies to each job the employee holds with different employers (different business numbers). If an employee leaves one employer during the year to start work with another employer, the new employer also has to deduct CPP contributions without taking into account what the previous employer paid. This is the case even if the employee has contributed the maximum amount during the previous employment.”
And the EI paragraph, in the same position in the guide: “If an employee leaves one employer during the year to start work with another employer, the new employer also has to deduct EI premiums without taking into account what the previous employer paid. This is the case even if the employee has paid the maximum premium amount during the previous employment.”
The restart only bites because the ceilings exist at all. At a single employer, CPP and EI deductions stop partway up the income scale and take-home pay steps up when they do, which is the mechanism our piece on when CPP and EI stop coming off your paycheque in 2026 follows through the year. A second employer sets that count back to zero.
The 2026 ceilings, and the most employment income can cost
| Figure | 2026 |
|---|---|
| Year’s maximum pensionable earnings (YMPE) | $74,600 |
| Basic exemption | $3,500 |
| Base employee rate and maximum | 4.95% / $3,519.45 |
| First additional rate and maximum | 1.00% / $711.00 |
| Base plus first additional | 5.95% / $4,230.45 |
| Year’s additional maximum pensionable earnings (YAMPE) | $85,000 |
| CPP2 employee rate and maximum | 4.00% / $416.00 |
| Total employee CPP for the year, at most | $4,646.45 |
| EI maximum insurable earnings | $68,900 |
| EI employee rate and maximum premium | 1.63% / $1,123.07 |
| EI employer rate and maximum premium | 2.282% / $1,572.30 |
Source: CRA T4127 Payroll Deductions Formulas, 122nd Edition, effective January 1, 2026, Tables 8.3 to 8.7. The 2.282% employer EI rate is the standard 1.4 times the employee rate. Those two maximums are what employment can cost; Schedule 8 Part 4 charges self-employment earnings separately and at its own rates.
Schedule 8 compares what was taken against what was owed
The CPP correction happens in Part 3 of Schedule 8, and two lines do most of the work. Line 1 totals pensionable earnings from box 26 of every T4 slip, capped per slip at the YAMPE; the 2025 version of the form prints that cap as $81,200, which was that year’s YAMPE. Line 6 gives one basic exemption of $3,500 for the year, however many employers there were. Part 2 prorates the exemption only for turning 18, a disability pension, a CPT30 election, or a return filed for someone who died, and a second job is not on that list.
The rest is comparison. Lines 9 and 10 split what was actually deducted, box 16, into its base and first additional halves at the ratio 4.95 to 5.95, printed on the form as 83.1933%. Lines 11 and 12 compute what was actually required. Line 22 computes the CPP2 required for the year. Line 24 nets the whole thing out. A positive line 24 is the overpayment and it goes on line 44800. A zero or negative line 24 produces no refund.
On EI, the CRA does the calculation
EI has a form of its own, and most people will never see it. Line 31200 claims what box 18 shows, up to the year’s maximum, and anything above that is the overpayment, which goes on line 45000. The difference from CPP is who works it out. For CPP the filer does: CRA’s line 44800 instruction is to complete Schedule 8 or Form RC381, “whichever applies, to calculate the amount, if any, of your overpayment to enter on line 44800 of your return”. For EI the agency does: “The CRA will calculate the overpayment for you”, with Form T2204, Employee Overpayment of Employment Insurance Premiums, there for anyone who would rather calculate it themselves. CRA’s own worked example on its line 31200 page is this article’s scenario:
“You worked for more than one employer during the year. Both employers deducted EI premiums from your pay and reported them in box 18 of your T4 slips. Since each employer calculates EI premiums separately, you may have paid more EI premiums than required for the year. When you file your tax return, the CRA will calculate any EI premium overpayment. If you overpaid, the excess amount will be entered on line 45000 of your tax return.”
Four job histories at 2026 rates
Four cases follow, but the rule behind them is worth stating first, because nothing in it stops at two employers. Schedule 8 line 1 caps pensionable earnings per slip rather than in total, so every employer past the first can duplicate up to a full year of both contributions, and the return gives that duplication back less any CPP2 no single payroll was in a position to deduct. Three employers each paying above the YAMPE, rather than the two in the third case below, put $9,292.90 on line 44800 and $2,246.14 on line 45000.
One employer, $120,000
Box 16 reads $4,230.45, box 16A $416.00, box 18 $1,123.07. Schedule 8 line 24 is $0.00 and there is nothing to refund. Line 30800 claims $3,519.45 of base CPP and line 22215 deducts $1,127.00 of enhanced contributions. On the employer’s side, $4,646.45 of CPP and $1,572.30 of EI, $6,218.75 in all. This is the baseline the other three are measured against.
Two employers, six months at each
The same $120,000, split as $60,000 at each employer, paid biweekly. Each employer prorates the basic exemption over its own pay periods: 13 of them at $134.61, so $1,749.93 at each and $3,499.86 across the year. ($3,500 over 26 periods is $134.6153, and CRA’s Table 6.1 prints $134.61, truncated rather than rounded, which is where the missing 14 cents goes.) The exemption, in other words, is close to neutral in this case. The duplication is in the rates.
Each employer deducts $3,465.88 of CPP and $978.00 of EI. Neither deducts a cent of CPP2, because neither one’s own payroll ever reached the $74,600 YMPE.
| Schedule 8 and the return | Amount |
|---|---|
| Total CPP deducted (box 16) | $6,931.76 |
| Total EI deducted (box 18) | $1,956.00 |
| Line 9, actual base | $5,766.76 |
| Line 11, required base | $3,519.45 |
| Line 10, actual first additional | $1,165.00 |
| Line 12, required first additional | $711.00 |
| Line 21, actual CPP2 | $0.00 |
| Line 22, required CPP2 | $416.00 |
| Line 20 | $2,701.31 |
| Line 23 | ($416.00) |
| Line 24, to line 44800 | $2,285.31 |
| EI excess, to line 45000 | $832.93 |
| Total refunded on the return | $3,118.24 |
Our arithmetic on Schedule 8’s own lines, at 2026 parameters.
Two employers, both above the YAMPE
Where each job on its own pays above the YAMPE, both employers run every deduction to its maximum: $4,230.45 of CPP, $416.00 of CPP2 and $1,123.07 of EI at each. The whole of the second slip is duplication, so line 44800 comes to $4,646.45 and line 45000 to $1,123.07, $5,769.52 together, exactly one complete year of CPP and EI returned.
Two jobs at the same time
Two concurrent part-time jobs paying $30,000 each, all year, run the other way. Each employer gives the full $3,500 exemption and Schedule 8 allows one, so line 24 comes to minus $208.25, which is 5.95% of $3,500 to the cent. There is no refund, and there is no bill either. CRA’s line 30800 page lists having had more than one employer as a reason a person “may have contributed less than the required amount”, and points to Form CPT20 for anyone who wants to top it up voluntarily.
Schedule 8 collects a contribution no pay stub ever showed
Line 23 in the table above is the part of this that nobody writes down. The two half-year jobs together paid $120,000, past the $85,000 YAMPE, so CPP2 of $416.00 is required for the year. Neither employer was ever in a position to deduct it, because neither one’s payroll crossed the threshold that triggers it. Schedule 8 takes it out of the refund instead. Deduct $2,285.31 from the $6,931.76 that was paid and $4,646.45 remains, which is precisely the full-year maximum, including a second additional contribution the worker never saw on a stub and will never find on a T4.
The worker is not short-changed by it. Line 22215 still allows the full $1,127.00 enhanced contribution deduction, that $416.00 included. The refund is simply net of a shortfall the form noticed and payroll could not.
The employers’ half of the overpayment is never refunded
Netted out, the worker ends the year in the same place whichever way the salary was earned: $8,887.76 deducted across two jobs, $3,118.24 of it returned, $5,769.52 borne, which is exactly what a single employer would have taken. The employers’ side does not net out.
The two half-year jobs cost their employers $9,670.16 in CPP and EI, against $6,218.75 for the same $120,000 paid by one. That is $3,451.41 more, and it comes back to neither of them. Where both employers pay above the $85,000 YAMPE instead, the excess is not $3,451.41 but $6,218.75, equally unrecoverable. CRA’s T4001 employers’ guide says so in both halves, immediately under the job-change paragraphs. On CPP:
“Any overpayments will be refunded to employees when they file their income tax and benefit returns. However, there is no provision in the Canada Pension Plan that would allow us to refund or credit the employer for their contributions in those circumstances.”
And on EI: “Any overpayments will be refunded to employees when they file their income tax and benefit returns. There is no provision in the Employment Insurance Act that provides a credit or refund to the employer in such circumstances.”
The statute behind the CPP half is Canada Pension Plan section 38, at subsection (3.2): “No refund may be made of any contribution required to be made as an employer’s contribution under section 9.” Each employer’s contribution was required, so none of it is in excess, so none of it is refundable. The employee is made whole and the two employers are not.
That claim is narrower than it may sound. Form PD24, the application for a refund of overdeducted CPP contributions or EI premiums, exists and employers do use it, within four years for CPP and three for EI. It covers employer errors: deducting past the maximum on the employer’s own payroll, or deducting from employment that was never pensionable or insurable. The job-change case is not an error, so PD24 does not reach it.
The two deadlines are different lengths
CPP gives four years. Section 38(1) requires the Minister to refund an overpayment “if application in writing is made to the Minister by the employee not later than four years … after the end of the year”, and CRA’s line 30800 page states it plainly: “you must ask for a refund of your CPP over-contributions no later than 4 years from the end of the year the overpayment occurred in.”
EI gives three. Employment Insurance Act section 96, at subsections (1) and (10), sets the window at “within three years after the end of the year”, and CRA’s line 31200 page says the same: a refund must be asked for “no later than three years from the end of the year the overpayment occurred in”. Filing on time makes the distinction moot, but a return left unfiled for a year with two employers runs out of time on the EI half first.
Four more pieces of small print are worth knowing before the return goes in:
- EI has a dollar floor. CRA, on line 45000: “If the difference is $1 or less, you may not receive a refund.”
- It may not arrive as money. Canada Pension Plan section 38(6) lets the Minister apply the amount to another debt owed to the Crown and notify the taxpayer instead of refunding it. CRA’s own line 44800 and 45000 pages put it more narrowly: the agency will refund the excess contributions or use them to reduce a balance owing.
- Insurable earnings of $2,000 or less are a special case. Section 96(4) returns the whole premium, “whether by one or more employers”, and CRA’s line 31200 instruction is then not to claim the premiums on line 31200 at all but to enter the amount on line 45000. Section 96(4.1) takes that refund back from anyone who is also a self-employed person to whom Part VII.1 of the Act applies and whose combined insurable and self-employment earnings, calculated under that Part, come to more than $2,000 for the year.
- Topping up a shortfall has its own date. Form CPT20, for anyone who wants to make up an under-contribution voluntarily, goes to CRA on or before June 15 of the following year.
Two jobs at once duplicate a tax credit as well as an exemption
The $3,500 basic exemption given twice in the concurrent case above is not the only once-a-year allowance that gets handed out twice because neither payroll can see the other. Income tax has a version of the same fault, and one place it shows up is the personal tax credits an employee claims on Form TD1. CRA’s T4001 puts the instruction to the employer:
“If your employee has more than one employer or payer at the same time and has already claimed personal tax credit amounts on another TD1 form, the employee cannot claim them again. If the employee’s total income from all sources will be more than the personal tax credits claimed on another TD1 form, they must check the box “More than one employer or payer at the same time” on page 2 of the TD1 form, enter “0” on line 13 on page 1 and not fill in lines 2 to 12.”
What separates the two programmes is not whether the duplication is noticed. It is what happens once it is. Schedule 8 notices the CPP exemption given twice and then lets it go, which is how the concurrent case lands at minus $208.25 with no refund and no bill. Nothing notices the duplicated personal credits during the year, and nothing forgives them either. Both employers withhold as though the full personal amounts belonged to their payroll alone, less income tax comes off across the year than the year turns out to need, and the gap arrives as tax owing at filing. A return can therefore refund CPP and EI on lines 44800 and 45000 and bill income tax on the same assessment. Our walkthrough of Ontario paycheque deductions and where gross pay goes takes apart that withholding calculation, personal credits included, as each employer runs it in isolation.
This is also the one part of the whole business a reader can prevent. The CPP and EI duplication cannot be stopped at source, because CRA tells both payrolls to ignore each other. The credits can: tick that box on the TD1 when the second job starts, enter zero, and leave the credit lines blank.
The other common shape of a multi-job year is a change that came with a severance payment, which brings its own line to the same return: what is paid on the way out has rules of its own about how much can be sheltered and what the shelter costs in contribution room. That is the subject of our piece on rolling severance into an RRSP.
How to check your own slips
None of this needs the four people above. Add box 16 and box 16A across every T4 for 2026, and add box 18 across the same slips. Anything above $4,646.45 on the first total and $1,123.07 on the second was overpaid, because neither figure can be exceeded for the year no matter how many employers there were. On the CPP side, Schedule 8 then nets off any second additional contribution the year required and no payroll was able to deduct, which is the $416.00 above.
Most of it then arrives without being asked for. The CRA calculates the EI overpayment itself. The CPP side needs Schedule 8 completed, which for anyone filing with tax software means the software fills it from the slips entered. The wait is the real cost, and it is longer than it sounds: a contribution taken off a cheque in January 2026 is not back in the worker’s hands until the 2026 return has been filed and assessed, well over a year later.
The overpaid part comes back at full value
One distinction is worth holding onto through all of this. The contributions a person was required to make are non-refundable tax credits, line 31200 for EI and line 30800 for base CPP, worth the lowest federal rate, 14% in 2026, plus the provincial credit. The part that was overpaid is not a credit and is not worth a fraction of itself. It comes back at a hundred cents on the dollar, because it was never owed.

Always consult a qualified financial advisor before making investment decisions. Every figure in this article is CRA’s own published 2026 amount or our arithmetic on CRA’s own forms, and all of it is first-hand. The 2026 CPP and EI parameters are from T4127 Payroll Deductions Formulas, 122nd Edition effective January 1, 2026, Tables 8.3 to 8.7 for the contribution rates and maximums and Table 6.1 for the per-period basic exemption; they were cross-checked against the 123rd Edition effective July 1, 2026, which carries the same $1,123.07 EI maximum and $3,519.45 base CPP maximum, so nothing in the piece turns on which 2026 edition is cited. The correction mechanism is read line by line off CRA’s Schedule 8 (5000-S8) Part 3, whose structure and line numbers are the T1-2025 form; two 2025 figures appear inside it and inside a quoted T4001 paragraph and both are labelled in the prose as 2025 figures ($81,200, which was that year’s YAMPE, and $71,300). The rule that each employer restarts the ceilings is quoted verbatim from T4127 Chapter 6 and from T4001 Employers’ Guide to Payroll Deductions and Remittances, which also carries the two sentences stating that there is no provision in either the Canada Pension Plan or the Employment Insurance Act to refund or credit the employer, and the TD1 instruction for an employee with more than one employer at the same time. The statutory provisions are the Justice Laws consolidations of the Canada Pension Plan section 38 and the Employment Insurance Act section 96, both current as of their 2026-11-02 page date. All 14 quotations in the piece were verified verbatim against the captured documents. The computed figures come from a control-tested engine written for this piece, which exits non-zero if any control fails; 38 controls ran clean, nine of which reproduce CRA’s OWN published 2025 maximums ($3,356.10, $678.00, $396.00, $1,074.00, $4,034.10, $1,077.48) and the 83.1933% split factor printed on the 2025 Schedule 8, which is what proves the algorithm rather than merely the arithmetic, and nine of which run inside the exact scenarios the article’s claims live in rather than only at the maximums. The chart is drawn from the same engine as the article so the two cannot disagree. A rounding trap is pinned by three controls: $3,500 over 26 pay periods is $134.6153, which a reader doing the division would round up, but CRA’s Table 6.1 truncates it to $134.61, and the engine is required to use CRA’s printed figure rather than its own arithmetic. No figure is estimated, forecast, indexed forward or taken from an aggregator.
